Introduction to Development Tools

GENERAL DESCRIPTION

The ADSP-2100 Family Development Software, a complete set

of software design tools, lets you program applications for this

family of DSP microprocessors that includes the ADSP-2101,

ADSP-2105, ADSP-2111, ADSP-2115, and the newest

members, the ADSP-2171 and ADSP-2181. With these tools,

an EZ-ICE In-Circuit Emulator, and an EZ-LAB Evaluation

Board, you can quickly and efficiently design your DSP

applications. The figure on page 1 (“System Development

Process Overview”) shows how the tools are typically used in

the development process.

DSP Software Development Tools

The software development tools include the following programs:

• System Builder • G21 C Compile

• Assembler • C Runtime Library

• Linker • CBUG C Source-Level Debugger

• Simulator • PROM Splitter

The System Builder reads your system specification file and

then generates an architecture description file that passes

information about your target hardware to the linker, simulator,

and emulator. Code generation begins with the creation of C

language and/or assembly language source code modules. These

modules are compiled/assembled separately and then linked

together to form an executable program (memory image file).

The highly readable algebraic syntax of the ADSP-2100 Family

instruction set eases programming in assembly language. Multiply-

accumulate instructions are written in the same manner as the

actual equation. For example, the algebraic statement

r = r + x*y

is coded in assembly language as

MR = MR + MX0*MY0.

The simulator configures program and data memory according

to the architecture description file and simulates the memory-

mapped I/O ports to let you debug your system and analyze its

performance. After simulating your system and software, use the

emulator with your prototype hardware to test circuitry, timing,

and real-time software execution. The PROM Splitter then

translates the linker-output executable file into an industry-

standard file format for a PROM programmer. Once you burn

the code into a PROM device and plug in an ADSP-21xx

processor to the target board, your prototype is ready to run.

Development software is available for the IBM (or IBM-

compatible) PC/AT and Sun4 workstation platforms.

DSP Hardware Development Tools

• EZ-ICE Emulators

• EZ-KIT Development Tools Packages

• EZ-LAB Evaluation Boards

The ADSP-2100 Family hardware development tools provide a

controlled environment for observing, debugging, and testing

activities in a full-speed target system. Our ADSP-2100 Family

EZ-ICE Emulators provide this control by replacing the target

processor or, in the case of the ADSP-2181, by assuming

control of the DSP through its ICE-Port. The EZ-ICE,

controlled by an IBM PC host computer, using a GUI interface

similar to the ADSP-2100 Family Simulators, lets you examine

and modify processor information such as registers and

memory.

The ADSP-2100 Family EZ-LAB Evaluation Boards let you test

coded applications in real time without a host or PC. At reset,

the processor on the ADSP-2100 Family EZ-LAB boots code

and program memory into its internal program memory from

the EPROM, and then executes the code.

EZ-KIT offers a complete development environment including

the ADSP-2100 Family Assembler/Linker and Simulator, an

ADSP-2100 Family EZ-LAB Evaluation Board. The EZ-KITs

for the ADSP-2101 and ADSP-2111 include an applications

handbook (Digital Signal Processing Applications Using the

ADSP-2100 Family Applications), plus a laboratory textbook

(Digital Signal Processing Laboratory Using the ADSP-2101

Microcomputer Laboratory Workbook with Introductory DSP

Experiments) and source code diskettes. The EZ-KIT Lite for

the ADSP-2181 is a lower cost starter kit that includes a subset

of the regular EZ-KIT software and documentation.

SOFTWARE TOOLS

SYSTEM BUILDER

The System Builder lets you define system hardware based on

ADSP-21xx processors with memory that can be specified as

RAM or ROM. It also lets you design ADSP-21xx Family

systems with paged external data memory, extending the

processor’s address space for additional data storage.

G21 C COMPILER

The G21 C Compiler is an optimizing ANSI compiler based on

the GNU gcc compiler. Applications written in C are compiled,

assembled, and linked to create executable ADSP-21xx

programs that can be debugged with an ADSP-21xx Simulator

or Emulator. It also supports in-line assembly code using the

asm() construct, which lets you use C expressions.

The G21 C Compiler contains optimization features to increase

execution speed of the resultant assembly code. These features

include algorithms to perform the following:

• Constant Folding

• Common Subexpression Elimination

• Loop Optimization and Strength Reduction

• Global and Local Register Allocation

• Parallelization

• Instruction Scheduling

C RUNTIME LIBRARY

The C Compiler comes with ANSI-standard functions and a set

of C-callable library routines commonly used in digital signal

processing to speed up development.

The ADSP-2100 Family C Runtime Library includes the ANSI-

standard and DSP-specific functions listed in Table I.

Interrupt Handling in C

The C environment supports hardware interrupts—a key feature

that facilitates programming. The signal handling functions of

the C library, signal, raise, and interrupt, process

ADSP-21xx interrupts such as serial port transmit and receive

interrupts, timer interrupts, and external interrupt request

signals.

The signal and raise functions direct execution to a specific

C interrupt service routine based on the type of interrupt that

occurs. This routing service allows the entire application to

be written in C without assembly language code. The signal

handling routines save and restore registers, and the overhead is

usually minimal compared to overall program execution time.

If you choose to write custom interrupt service routines in

assembly language, you can use the signal and raise

functions to set up service routines in the C environment.

ASSEMBLER

The Assembler reads source files containing ADSP-2100 Family

assembly language and generates a relocatable object file. The

Assembler includes a preprocessor that lets you use C

preprocessor directives such as #define, #include, #if,

#ifdef, and #else in assembly code.

Assembler directives define code modules, data buffers, data

variables, and memory-mapped I/O ports. Either assembler

directives or C preprocessor directives define and invoke

macros.

LINKER

The Linker processes separately assembled object files to create

a single executable program. It assigns memory locations to

code and data in accordance with the architecture file defined

by the System Builder.

The Linker also generates symbols (variable names and program

labels) in the processed files, which the simulator, emulator, and

the CBUG C Source-level debugger use to perform symbolic

debugging.

PROM SPLITTER AND HIP SPLITTER

The PROM Splitter translates an ADSP-21xx executable

program into a file used to program PROM memory devices.

The PROM Splitter’s output file can be generated in Motorola

S Record or Intel Hex Record format. Motorola S2 format is

supported for byte stream output.

The HIP Splitter utility generates ADSP-2111 and ADSP-2171

programs to be downloaded from a host processor through the

DSP’s Host Interface Port (HIP). The HIP Splitter’s output file

can be generated in Motorola S Record or Intel Hex Record

format.

Both the PROM Splitter and the HIP Splitter have a boot

loader option that enables loading of external memory.

ADDS-21xx-TOOLS

SIMULATORS

There is a simulator for each ADSP-2100 Family processor that

provides instruction-level simulation of program execution. The

Simulator models system memory and I/O according to the

contents of the system architecture file, and provides windows

to display different portions of the target system hardware. The

Graphical User Interface (GUI) lets system designers inter-

actively observe and alter register and memory contents,

providing a powerful debug environment. Simulator commands

can be entered from the mouse or keyboard.

Features offered by the ADSP-2100 Family Simulators include

the following:

• Program and Data Memory Simulation

• Memory-Mapped I/O Port Simulation

• Interrupt Simulation

• Program Booting (from PROM or host processor) Simulation

• Code Execution Pattern Profiling for Program Optimization

• On-Line Help

• Reconfigurable Windows

• Same User Interface as EZ-ICE Emulators

CBUG C SOURCE-LEVEL DEBUGGER

The Simulators are seamlessly integrated with the CBUG C

source-level debugger. CBUG supports the following

operations:

• Run, Step, Next, and Finish Program Execution Commands

• C Source Code Breakpoints

• Local and Global Variable Display with Auto Refresh

Examines Value of Variables at Previously Executed

Instructions

• Symbol Look-Up

EZ-KIT Lite

The ADSP-21xx EZ-KIT Lite is a low-cost, easy to use

development platform on which you can quickly get started with

your ADSP-2100 Family based DSP software design. The EZ-

KIT Lite is a complete development system package that

includes:

• ADDS-2181 EZ-LAB Board

• MS-Windows 3.1 Based Monitor Software

• Development Software Kit (upgradable to complete ADSP-

2100 Family Development Software package for full-featured

development of final systems)

• Demo Programs

- Digital Filtering

- Speech Compression

- FFT

- Echo Cancellation

- DTMF Tone Generation

- MPEG Audio Playback

The EZ-Kit Lite uses the ADDS-2181 EZ-LAB as a

development platform on which you can develop software

applications for any of the ADSP-2100 Family DSPs. This is

possible because the ADSP-2181 represents a superset of the

features of the ADSP-2101/2105/2111/2115/2171 processors.

With the ADSP-2181’s 32K words of on-chip RAM, there is no

need for additional RAM devices on the EZ-LAB board. The

board simply requires connection to power, an analog input

source, and amplified speakers to be able to run audio

applications and demos.

The EZ-LAB board can run in a stand-alone mode, or it can be

connected to the RS-232 port of your PC. A Windows-based

monitor program lets you interactively download programs and

interrogate the ADSP-2181 (see Figure 1). The board comes

with a socketed EPROM so that you can run the monitor

program or demonstrations provided—or you can plug in an

EPROM containing your own code.

ADDS-21xx-TOOLS

An AD1847 SoundPort® codec is connected to the DSP

through serial port 0. The AD1847’s sampling rate can be

programmed for analog-to-digital and digital-to-analog

conversion from 5.5 kHz to 48 kHz. The high-speed

synchronous serial port carries all of the data, control, and

status information between the DSP and the codec. The codec

may be disconnected from the serial port if the port is needed

for other purposes. Input to the codec can be a microphone,

signal generator, or any other high impedance source, while the

resulting output signal can drive an amplified speaker or the

line-level input of other audio equipment.

As with all EZ-LAB evaluation boards, the ADDS-2181 EZ-

LAB provides a manual power-on reset button, an interrupt

button, and an LED controlled by the FL1 Flagout pin.

Although the IDMA port on the ADSP-2181 is not used on the

EZ-LAB board, all of the IDMA signals are available through

an expansion connector.

Device Specific EZ-KITs

Two other EZ-KITs are available for specific members of the

ADSP-21xx Family.

ADSP-2101 EZ-KIT

The ADSP-2101 EZ-KIT is a starter package for system

development that combines the ADSP-2101 EZ-LAB with an

Assembler software package and a Simulator. This EZ-KIT

may also be used for developing applications targeting the

ADSP-2105 and ADSP-2115 processors.

ADSP-2111 EZ-KIT

The ADSP-2111 EZ-KIT is a starter package for ADSP-2111-

based system development that combines the ADSP-2111 EZ-

LAB with an Assembler software package and a Simulator.

ADSP-2100 FAMILY EZ-LAB EVALUATION BOARDS

The ADSP-2100 Family EZ-LAB Evaluation Boards are a

complete DSP system on a single board that lets you test coded

applications in real time. Some EZ-LABs provide for booting

from EPROM and others allow upload/download capabilities

from a host PC. Table II lists the features of the different

versions of the EZ-LAB available for the ADSP-2100 family.

ADSP-2181 EZ-LAB

See the discussion of the ADSP-21xx EZ-KIT Lite for

information on the ADSP-2181 EZ-LAB.

ADSP-2101 & ADSP-2111 EZ-LABs

The ADSP-2101 and ADSP-2111 EZ-LABs are similar in

design and use. A complete DSP system on a single board, the

EZ-LAB lets you test coded applications in real time without an

external host. At reset, the processor on the EZ-LAB boots

code and programs memory data into its internal program

memory from a 64K × 8-bit EPROM and then executes the

code.

The ADSP-2101 and ADSP-2111 EZ-LAB provide manual

control of several functions. For example, push-buttons activate

the IRQ2 interrupt and FLAG IN pins, and an on-board

hardware RESET switch resets the EZ-LAB.

In addition to the standard features of the ADSP-2101, the

ADSP-2111 includes a Host Interface Port (HIP) that is also

included on the ADSP-2111 EZ-LAB board as a separate

connector. The ADSP-2111 EZ-LAB board replaces the

ADDS-2101’s User Interface Connector with an Expansion

Connector that allows access to the external address and data

bus and control lines of the DSP.

The demonstration boards operates alone when you attach them

to a +5 V dc @ 1 amp and ±12 V dc power supply with a

common power return.

Demo Programs

Use the prepared demonstrations on the ADSP-2101 and

ADSP-2111 EZ-LABs, which include speech and graphics

applications, to familiarize yourself with and to evaluate the

ADSP-2100 Family processors. The EPROM is mapped into

the boot memory space. Upon reset, the processor loads boot

page 0 into its internal program memory and begins execution.

During program execution, any one of the eight boot pages can

be loaded into the processor under software control.

The demonstrations use the microphone and speaker

connections for audio input and output. The ADSP-2101 and

ADSP-2111 EZ-LABs have four DAC outputs to connect to an

oscilloscope for display. In addition to these outputs, these EZ-

LABs have an expansion connector and a serial port connector

for synchronous serial data I/O. The connectors let you access

the serial ports, external address bus, external data bus, control

signals, interrupt lines, and the host interface port.

Analog I/O

A codec attaches to the processor’s serial port 0 on the ADSP-

2101 and ADSP-2111 EZ-LABs. Configure the other serial

port for interrupts and flags by changing on-board jumpers. The

input signal to the codec can be a microphone, signal generator

or any other high impedance source, and the resulting output

signal can drive a small speaker.

The ADSP-2101 EZ-LAB and ADSP-2111 EZ-LABs contain

socket-mounted 16.384 MHz crystals. The socket lets you

replace the crystal to achieve different clock speeds.

ADSP-2105 and ADSP-2115 System Development

The ADSP-2101 EZ Development Tools support the ADSP-

2105 and the ADSP-2115 because their architectures are

subsets of the ADSP-2101. The ADSP-2105 has one serial port

(instead of two), and both the ADSP-2105 and the ADSP-2115

have half the internal memory of the ADSP-2101. Use the

ADSP-2101 EZ-LAB to evaluate, and the ADSP-2101 EZ-ICE

for emulation and debugging of both the ADSP-2115 and

ADSP-2105 target systems.

The ADSP-2171 EZ-LAB

The ADSP-2171 EZ-LAB is an easy to use hardware

development platform on which you can quickly get started with

your ADSP-2171-based application. Applications can be run in

real-time with or without a PC host. This EZ-LAB has four

modes of operation:

• EZ-LAB can be controlled from your PC host when the

board is plugged into the PC backplane; programs can be

downloaded and uploaded, the processor can be reset, and

program execution can be initiated.

• EZ-LAB can be interfaced to an EZ-ICE Emulator; through

the EZ-ICE, programs can be loaded into EZ-LAB, program

execution can be initiated and halted, register and memory

locations can be examined and altered, and other debugging

operations can be performed.

• EZ-LAB can be controlled from a host plugged into the Host

Interface Port (HIP) connector when the EZ-LAB is running

in a stand-alone configuration.

• EZ-LAB can be controlled from software contained in a boot

EPROM when the board is used in a stand-alone configuration.

The ADSP-2171 interfaces directly to its program and data

memories. The expansion connector may be used to interface

to external devices. The DSP is also connected to indicator

lights for data output and to pushbuttons for manual data input.

Modular Analog Front End (MAFE) daughter cards can be

connected to the ADDS-2171’s MAFE Interface Connector,

allowing the DSP to communicate with a variety of I/O

peripherals through memory mapped registers.

Modular Analog Front End (MAFE)

The MAFE specification provides a standard configuration for

connecting analog I/O devices to MAFE compatible EZ-LAB

products. This specification is used by Analog Devices and

third-party vendors to design and manufacture add-on adapters

which contain, for example, A/D and D/A converters. These

A/D and D/A converters can communicate data either serially

or on a parallel bus. These devices can also contain a number

of internal control registers as well as some external control

lines.

If the MAFE device uses parallel data transfer, the memory

location designated as the MAFE data is written to or read from

in order to transfer data to/from the MAFE device. Data for a

control register and data which represents the analog sample are

both transferred in this manner. If the MAFE device uses a

serial data transfer, the appropriate serial port of the DSP is

used. Transfer of control data may also need to be done in a

parallel fashion.

ADSP-2100 Family EZ-ICE Emulators

The ADSP-2100 Family EZ-ICE in-circuit emulators are used

for testing and debugging an ADSP-21xx-based system. The

EZ-ICEs make it easy to view and manipulate the data needed

to debug your DSP applications. Table III lists the features of

each version of EZ-ICE currently available for the ADSP-2100

family.

Control and debug features include single-step capabilities, with

or without register displays, and multiple breakpoint selections.

At power-up, the host PC automatically resets and performs a

diagnostic check to ensure that both host memory and the EZ-

ICE are functional; it automatically displays any failures found.

ADSP-2181 EZ-ICE TOOLS

Features

The ADSP-2181 EZ-ICE In-Circuit is a development tool for

debugging programs running in real time on a target system

based on the ADSP-2181. It includes all of the standard

functionality of the other EZ-ICEs, with the added advantages

of full speed emulation, a smaller connector interface, and ease

of use.

The ADSP-2181 EZ-ICE provides a simpler target board

connection that requires fewer mechanical clearance

considerations than other EZ-ICE Emulators by utilizing the

ICE-Port™ emulation interface built into the ADSP-2181 (see

Figure 3). The ICE-Port interface requires little more than a

14-pin header connector to implement it. All of the standard

functionality of the other EZ-ICEs are provided, with the added

advantages of full speed emulation, a very small connector

interface, and ease of use.

EZ-ICE Software

Like the rest of the ADSP-2100 Family EZ-ICE Emulators, the

ADSP-2181 uses the same EZ-ICE software and GUI interface

design as the other EZ-ICEs and the ADSP-2100 Family

Simulators. This makes the development process easier as the

tools share so much commonality in use.

ADSP-2101 AND ADSP-2111 EZ-ICE TOOLS

Features

These versions of the EZ-ICE are designed with a PGA

connector protruding from the bottom of the probe board that

fits into the processor socket on the target system. Connector

adaptors for PQFP and TQFP are available. The ADSP-2101

EZ-ICE is also used in developing systems based on the ADSP-

2105, ADSP-2115, and ADSP-216x DSPs. Systems based on

the ADSP-2111 use the ADSP-2111 EZ-ICE.

EZ-ICE Software

The ADSP-2101 and ADSP-2111 EZ-ICE Emulators use the

same EZ-ICE software and GUI interface design as all of the

ADSP-2100 Family EZ-ICEs and the ADSP-2100 Family

Simulators. Development productivity is increased by making

your data easier to view and manipulate when debugging. In

addition, you can view relevant information without switching

between screens and can obtain on-line help for the currently

selected window. The user interface is similar to the one used

with the ADSP-2100 Family Simulators, making both tools

easier to use.

ADSP-2171 EZ-ICE TOOL

Features

The ADSP-2171 EZ-ICE In-Circuit Emulator is a development

tool for debugging programs running in real time on a target

system based on the ADSP-2171 processor. This is made

possible through the use of the ADDS-21xx EZ-ICE Board

which differs from other EZ-ICE models in its use of a pair of

dedicated header connectors that allow it to plug directly onto

the target board and interface with the target DSP (see Figure

2) or to use an adaptor to clip onto the target DSP itself,

depending on the device package used.

EZ-ICE Software

Like the rest of the ADSP-2100 Family EZ-ICE Emulators, the

ADSP-2171 uses the same EZ-ICE software and GUI interface

design as the other EZ-ICEs and the ADSP-2100 Family

Simulators. This makes the development process easier as the

tools share so much commonality in use.

EZ-ICE EMULATORS: SPECIAL CONSIDERATIONS

Connector Requirements

The PGA probe’s footprint that protrudes from the bottom of

the ADSP-2101 and ADSP-2111 EZ-ICE boards fits into the

DSP chip socket on your target system. Note that the socket

must allow sufficient clearance for the ADSP-21xx’s footprint.

The ADSP-2171 EZ-ICE attaches to the target DSP chip by

simply clipping over the PQFP package version of the DSP. An

alternate approach is needed for use with the TQFP package

version of the DSP. Because the TQFP packaged chip and its

leads are too small for a probe, the target board should include a

pair of header connectors to allow the EZ-ICE board to plug

directly onto it in order to interface with the DSP chip. Both

methods are illustrated in Figure 2.

An alternate approach is required for the TQFP chip package.

Because of the extremely low profile of the surface mount

TQFP package, it is not practical to use a snap-on adaptor or

probe. Thus, in order to use the EZ-ICE, it is necessary to

provide a pair of header connectors on the target board that the

ADDS-21xx EZ-ICE board can plug directly onto. Extra space

around the adaptor and extra through-holes to the PQFP

package are not required to let you use the same PCB in

production. Dimensional requirements for placing the headers

is also shown in Figure 2.

ADSP-2181

There is no need for a surface mount adaptor for the ADSP-

2181 EZ-ICE. Instead, the ICE-Port Emulator Interface allows

for a simple 14-pin connector interface between the target board

and the EZ-ICE.

DESIGNING AN EZ-ICE COMPATIBLE TARGET

SYSTEM FOR THE ADSP-2181 AND THE ADSP-2171

ADSP-2181 Target System Requirements

The ADSP-2181 has on-chip emulation support and a special

set of pins that interface to the EZ-ICE called the ICE-Port.

The ICE-Port allows in-circuit emulation without replacing the

target system’s processor or overriding it with a probe, requiring

only a simple 14-pin header connector to interface to the EZ-

ICE (see Figure 3).

Table IV lists the pins and functions used in the ADSP-2181’s

ICE-Port emulation interface.

NOTE

*These ADSP-2181 pins must be connected only to the ICE-Port connector in

the target system. These pins have no function except during emulation. Keep

all traces as short as possible; no longer than 3 inches.

GUI Interface

EZ-ICE software uses a Graphical User Interface (GUI) to

increase development productivity by making your data easier to

view and manipulate—without switching between screens—

when debugging. In addition, you can obtain on-line help for

the currently selected window. The GUI user interface design is

the same one used with the ADSP-2100 Family Simulator

software, making both tools easier to use.

Clock Speed

EZ-ICE runs at full speed. There is no degradation of

processor performance other than BR, BG, and RESET, which

are slightly delayed. A jumper is used to select either the target

system clock or the EZ-ICE clock. The oscillator socket lets you

use other oscillator devices to achieve different clock speeds.

Memory

The ADSP-2101, ADSP-2111, and ADSP-2171 EZ-ICE each

have 8K × 24-bit overlay program memory and 16K × 16-bit

overlay data memory. You can either run programs from target

system memory, emulator overlay memory, or from a combination

of both. The overlay memory option is jumper-selectable.

Additional Equipment Required

EZ-ICE requires a +5 V dc power supply capable of supplying

1 A of current.

3-Volt Emulation

The 3-Volt Emulation Converter Board may be used with the

ADSP-2101 EZ-ICE to enable emulation of ADSP-2103 (3 V)

systems.

SURFACE MOUNT ADAPTORS

ADSP-2101/ADSP-2105/ADSP-2115

Several surface mount adaptors are available for emulation of

the ADSP-2101. For example: for the 68-pin PLCC package of

the ADSP-2101 and ADSP-2105, a PGA-to-PLCC adaptor is

available from the vendors listed at the end of this data sheet.

For the 80-pin PQFP package of the ADSP-2101, a 68-pin

PGA to 80-pin PQFP adaptor is also available.

The ADDS-2101-PGA/PQFP, a surface-mountable PGA-to-

PQFP adaptor, provides a footprint that exactly matches the 80-

pin package. This solution does not require extra space around

the adaptor or an extra through hole to the PQFP package to let

you use the same PCB in production. The PGA-to-PQFP

adaptor is surface mounted in the usual manner, and the PGA

connector of the ADSP-2101 EZ-ICE or ICE can be directly

plugged in.

ADSP-2111

The ADDS-2100-PGA/PQFP, a surface-mountable 101-pin

PGA to 100-pin PQFP adaptor, matches the ADSP-2111

package footprints. This solution does not require extra space

around the adaptor, and you can use the same PCB in

production. The PGA-to-PQFP adaptor is surface mounted in

the usual manner, and the PGA connector of the ADSP-2111

EZ-ICE can be directly plugged in.

ADSP-2171

The ADSP-2171 EZ-ICE Emulator is designed for compatibil-

ity with the surface mountable 128-pin PQFP package using an

adaptor card which plugs onto the ADDS-21xx EZ-ICE board

and then snaps onto the PQFP chip. This is illustrated in Figure

3. Extra space should be allowed around the PQFP chip to

allow clearance for the adaptor.

ADDS-21xx-TOOLS

The EZ-ICE uses the ICE-Port’s EE (emulator enable) signal to

take control of the target ADSP-2181. This causes the DSP to

automatically use its ERESET, EBR, and EBG pins instead of

the RESET, BR, and BG pins. The BG output is tristated.

And, unlike many other emulators, these signals do not need to

be jumper-isolated in your system when the EZ-ICE is installed.

Restrictions

If you are using the external memory bus in your target system,

all memory strobe signals being used on the ADSP-2181 (RD,

WR, PMS, DMS, BMS, CMS and IOMS) must have a 10 kΩ

pull-up resistor connected when the EZ-ICE is being used. The

pull-up resistors are necessary because there are no internal

pull-ups to guarantee their state during prolonged tristate

conditions resulting from typical EZ-ICE debugging sessions.

These resistors may be removed at your option when the EZ-

ICE is not being used.

Interconnection

The EZ-ICE for the ADSP-2181 uses a 10-inch long ribbon

cable to connect to the target board. The ribbon cable is

permanently attached to the EZ-ICE and is terminated with a

standard 2-row × 7-pin (0.100 × 0.100 inch pin spacing) female

IDS connector. The mating ICE-Port connector on the target

board should be a 2-row × 7-pin male (0.025-inch square pins,

minimum 0.20-inches long) pin strip header (available from

such vendors as 3M, McKenzie, and Samtec). This connector

is necessary if you intend to use the ADSP-2181 EZ-ICE. The

length of traces between this connector and the DSP should be

kept as short as possible; no more than 3-inches long. Figure 4

shows the target board connector and the pin assignments. Pins

shown with a “*” notation must be connected only to the ICE-

Port connector.

ADSP-2171 Target System Requirements

To provide emulator interface capability to your target DSP

board design, you must add a pair of 45-pin male headers to

your board. The EZ-ICE’s ADDS-21xx Emulator Board (EB)

plugs directly onto the connectors, becoming a daughter card

to your target system. Figure 2 shows how this is accomplished

and some of the critical dimensions involved. (Note: Pin strip

headers should be SAMTEC part number TSW-115-07-S-T

or equivalent.) It is important that there is approximately

0.40 inches clearance around the connectors.

Do not connect a separate power supply to your EZ-ICE board

when it is inserted in your prototype through the emulator

connectors. The power connectors on the EZ-ICE EB board

are for stand-alone operation only.

(Note: For use in a stand-alone mode, a DSP target card is

supplied with the EZ-ICE and plugs onto the EZ-ICE through

the same pair of connectors described above.)

Also, while this scheme may be used for either the PQFP or

TQFP DSP packages, one alternative does exist for the PQFP

target system. This alternative involves a snap on PQFP

adaptor, also shown in Figure 1, that plugs onto the EZ-ICE EB

board and snaps onto the DSP chip.

Using EZ-LAB and EZ-ICE Together

Combining an EZ-LAB with an EZ-ICE forms a high speed

DSP evaluation and development environment with an

interactive, window-based debugging interface. For the ADSP-

2101 and ADSP-2111 EZ-LAB/EZ-ICE combinations, remove

the processor device from its socket on the EZ-LAB board and

plug the EZ-ICE into the DSP’s empty socket. For the ADSP-

2171 EZ-LAB/EZ-ICE combination, simply snap the EZ-ICE

with its PQFP adaptor onto the EZ-LAB’s processor. And for

the ADSP-2181 EZ-LAB/EZ-ICE combination, simply plug the

EZ-ICE’s ribbon cable connector onto the EZ-LAB’s ICE-Port

connector. These combinations let you prototype and evaluate

your application without initial time investment in hardware

design.

Table V lists the pinout for the female connectors on the EZ-

ICE’s EB board. See the ADSP-2171 Data Sheet for TQFP pin

Table VI lists the ADSP-2171’s emulator-only pins that

correspond to the EZ-ICE connector pins. These emulator-

only pins are listed on the ADSP-2171 data sheet as no-

connects (NC). Also, note that the emulator-only pins must be

connected only from the DSP to the emulator connector. These

pins have no function except during emulation. Keep all

connections as short as possible. The scheme of mounting the

connectors on opposite sides of the DSP is best.

Do not connect a separate power supply to your EZ-ICE board

when it is inserted in your prototype through the emulator

connectors. The power connectors on the EZ-ICE EB board

are for stand-alone operation only.

(Note: For use in a stand-alone mode, a DSP target card is

communication register. This register enables signaling from the DSP to the PC without slowing down

the DSP for bus accesses to check status. The card also provides access to the boot section of the

expansion card for downloading programs and restarting the DSP so the developer can design and test

programs without needing to burn EPROMs.
